Rare late state of De Vaugondy's map of America, updated to include the details of all three of Cook's voyages.

The Northwest Coast of America has again been heavily revised to include the discoveries up to 1800, with the earliest hint of the course of the Columbia River shown, albeit an amalgam of the Columbia and Frazier Rivers.

The Northwestern Plains are shown as a large blank, transitioning from the sea of the West and similar misconceptions, to the pre-Lewis & Clark and Humboldt period.

The United States is shown in outline color, along, separated from the region purchased from France by the Americans (Louisiana Purchase).

Lacks text panel on the right, which was present on earlier states.

Didier Robert de Vaugondy Biography

Didier Robert de Vaugondy (ca. 1723-1786) was the son of prominent geographer Gilles Robert de Vaugondy and Didier carried on his father’s impressive work. Together, they published their best-known work, the Atlas Universel (1757). The atlas took fifteen years to create and was released in a folio and ¾ folio edition; both are rare and highly sought-after today. Together and individually, father and son were known for their exactitude and depth of research.

Like his father, Didier served as geographer to King Louis XV. He was especially recognized for his skills in globe making; for example, a pair of his globes made for the Marquise de Pompadour are today in the collection of the Municipal Museum of Chartres. Didier was also the geographer to the Duke of Lorraine. In 1773, he was appointed royal censor in charge of monitoring the information published in geography texts, navigational tracts, and travel accounts.
